Pneumatic taking-off device of unmanned aerial vehicle

Abstract

The invention discloses an unmanned aerial vehicle pneumatic launching device, which comprises a base, a launching trolley, a launching tube, and an air storage tank. The launch trolley is connected, the front end of the launch tube is provided with a locking mechanism, and the rear end is provided with a pressure sensor; the rear end of the base is provided with a controller, and the controller is connected with the pressure sensor, locking mechanism and solenoid valve; the launch trolley passes through The pulley is installed in the chute on the base; the front end of the upper surface of the base is provided with a buffer device; the front end of the base is higher than the rear end, and a tripod with a lifting rod is arranged at the front end of the base. The launch angle of the UAV is adjusted by the tripod, the control system controls the air storage tank to inflate the launch tube, and the launch car advances along the base to drive the UAV to launch, and the buffer device blocks the launch car and stops it. The invention improves the safety and reliability of launch.

Description

technical field [0001] The invention relates to a launching device, in particular to a pneumatic launching device for an unmanned aerial vehicle. Background technique [0002] As the result of modern scientific and technological progress, drones have the advantages of high mobility, low cost of use, and simple maintenance and use. Therefore, drones are used in aerial photography, agriculture, plant protection, express delivery, wildlife observation, surveying and mapping, disaster relief and other fields. widely used and plays an important role. In many cases, UAVs cannot take off autonomously, so there must be additional devices or technologies to help UAVs take off. At present, UAVs mainly take off by taxiing, vertical takeoff and ejection; Take-off has high requirements on the site, which is difficult to achieve in the field; vertical take-off requires that the UAV must have a powerful engine to generate enough lift, and most UAV engine power cannot meet; catapult take-o...

AI Technical Summary

Problems solved by technology

The rubber band ejection frame has a large mass, takes up a large space, is inconvenient to carry, and the launching power and power adjustment range are relatively small, and the scope of application is small; the above-mentioned problems also exist in the spring ejection frame, and many ejection frames still exist in some Other problems, such as low launch success rate due to single launch angle, low safety, easy to cause accidental injury, low release reliability, low portability, etc.
